I am also getting the same error.
I tried the sequence suggested by Mr. Junior but no luck.
I think it is due to port closure. I have to ask the Network team to sniff it to find if that is the issue because I am having trouble in exporting file to server as well.
Otherwise the studio is working fine. I am not really sure what is the issue.
Please let us know if any advice for us.
Best Regards,
SS
